Is the servo disconnected?
They can act up aswell due to corrosion and such.

Ahh fair enough then. Every bike is different lol

You guys have given me a lot to work with...

No, I definitely won't be riding it anywhere when it's running like this.

I'll print off this whole thread and show it to my friend who knows a lot more about bikes than me...

Thanks

Will have a shot of it over this winter, got big plans for the old DT in the next few months so will report back

@irongamer727 You probably won't gain higher revs, as unfortunately, the ability to rev higher is lost with the bigger bore.

But yes, you will be able to dial in the ignition much more towards the bigger cylinder.

I'd have thought there would be some nice gains with this and the bigger bore.

@ninja that’s better!

@scrimsmustang it seems to be sorted now put a stiffer spring in

@ricky0115 don’t use rtv silicone it ends up in your reed cage

@perithtv I've been there too few months ago. Soaking , heating etc etc nothing
Take off everything possible what can restrict you in the back and chop the bolt on as much places as angle grinder let you. I had 4 cuts and lifted the pieces off. Bought brand new guts for it and there is more grease then metal on it 😂 damaged my axe on it too 😁

When I bought my bike carb was leaking from overflow pipe all the time, when tank valve was open. I opened the carb and the reason was that, the float valve was upside down! I turn it to right way and overflow stop immediately!!! Check that!

Cant see why you wouldt want to get better filtration...

Airfilter oil is pretty cheap, and the filter is made to flow this way.
Youd' be surprised how much crap it catches when you clean it.

@Calum ??

@Zrako when I rebuilt my bike my servo would get stuck when turning on the ignition how ever I kept turning the key and it sorted its self out no problem

It says 3nc-00 on cdi

@Calum thanks! What revs do the the dts go to on full choke

@Mightyman Nah the DTRE's were given full YPVS servos.

Although you make a good point, the YPVS does shut off at 10'000 rpm as a restriction.

But the point here is the build up of NoX's gases. So whilst they did shut off, the normal person would be part throttle anyway. And if you were pinning it, well you would expect it to give up eventually and this might be why.

@jgr72 if I remember I'll look at my other bike it might have the size of pipe printed on it

@Calum figured so thanks

@castrolsniffer will do now I know what it is thanks.

Have you earthed the powervalve?
